Bad weather from Tropical Storm Hermine forced the cancellation of a planned one-mile sand race on Saturday. Since Friday, organizers had signaled their intent to proceed with Sunday’s event and a related 5K. But they also encouraged participants to keep checking for updates and subscribe for alerts by text message. Late Saturday, organizers posted an update on the event’s website and sent word by text that the event was on.

“Tropical Storm Hermine is out and the runners are in,” Rock ‘n’ Roll Half Marathon tweeted about half an hour after the start.

A spokesperson, Dan Cruz, confirmed the race began on time with pleasant conditions for the runners. So far so good, he added.

Still, high winds have caused changes to some of the planned elements on the course, according to the update on the event’s website late Saturday night.

Signs at the start and finish will be limited or unavailable, the notification said. There will be modified mile markers and no clocks. Tents and banners will be limited, fewer bands will perform from stages along the course and runners may find delays at water stations, since winds might blow over the cups.

“Runner safety is and will continue to be our top priority,” organizers said in the update.

An estimated 15,000 runners from 50 states and five countries had registered to participate in the event, the spokesperson said earlier.

The starting point of the races was the Virginia Beach Convention Center, 1000 19th St.
